Curious what Ice Cream Sandwich would be like on your HTC Rezound? If you can’t wait for the update to roll out, today’s your lucky day. ICS builds for HTC Rezound got leaked online. The available builds are unfinished which means you can expect a few bugs here and there. But they can be used as daily ROMs for things like texting, making calls, or connecting to the internet.

The leaked builds for Verizon’s HTC Rezound are based on Android 4.0.3 Ice Cream Sandwich and include one significant upgrade – Sense 3.6. The fresh UI resembles the interface of Sense 4.0 but is optimized for models that came before the HTC One series. If you want to give it a spin, you can choose from three stock updates and one pre-rooted build. Stock builds are recommended if your HTC Rezound still has warranty. But if you’ve rooted it before, the pre-rooted firmware won’t do any harm. I prepared two installation guides for you – one for flashing the stock ICS ROM and another for rooting it.
